CORRECTION
FACTORS
FOR
OPERATION
WITH
GLYCOL
The
following
correction
factors
are
to
be
used
only
if
the
indoor
unit
is
installed
in
any
internal
area
of
the
building
subject
to
low
temperatures
and
with
the
judgment
of
adding
a
certain
quantity
of
glycol
for
protecting
the
hydraulic
circuit.

Water

correction
factor.

Pressure
drops
correction
factor.
The
water
flow
rate
and
pressure
drop
correction
factors
are
to
be
applied
directly
to
the
values
given
for
operation
without
glycol.
The
water
flow
rate
correction
factor
is
calculated
in
order
to
get
the
same
temperature’s
difference
that
would
be
obtained
without
glycol.
The
pressure
drop’s
correction
factor
takes
into
account
the
different
water
flow
rate
obtained
from
the
application
of
the
water
flow
rate
correction
factor.
